Spectrum of bacterial pathogens in uncomplicated and complicated urinary tract infections.

The spectra of bacterial organisms of urinary tract infections (UTI) in patients with and without abnormalities in the urinary tract (complicated and uncomplicated UTIs) are compared. Data from the United Kingdom and the Federal Republic of Germany are included. In addition, the susceptibility of the pathogens to antibiotics (for oral or parenteral application) in both countries are compared. In conclusion, rational antibiotic therapy of complicated UTIs should strictly follow the antibiogram of the causative organism. For therapy of uncomplicated UTIs, the regional state of antibiotic susceptibility of the pathogens according to geographical location should be considered and kept up to date.
